I know, that there were also cars, which were only finished at AMAG, but this one has no 'American' Tag, no VIN plate on the dash - the VIN Number has no digit (letter) for the plant - normal for AMAG Cars - and - this is the point for me - all the glass was produced in the Netherlands - if it were a Hamtramck car, it should have Mopar glass.
Btw:
I have two Hamtramck cars built for export, partly finished in Austria - they have VIN plates on dash with complete numbers, buildsheets etc.
